His paper seeks to focus on the contribution information resources and libraries as elements bringing in added value to information and/or knowledge production and to analyze the tripartite relationship among such concepts as ‘added ‘value’, ‘elements that create value’ and ‘value/performance measurement’. In this context, the author introduces a new ‘conceptual model’ which is based on an original methodology that may be called ‘documentary evidence’ in order to measure the value created by information resources and libraries in the literature world which is the output of knowledge production. The model in endowed with a methodology that is capable of reaching answers to a range of questions including the following: the level of international and national scale accessibility to and retrieval of publications that contribute to the knowledge production process; information resources that scientists prefer most in producing knowledge (i.e. printed/electronic media); distribution of most preferred materials in terms of language, authors and publishers as well as age and types of materials; and availability of preferred information resources in the libraries of universities they are presently working at. In this respect, the paper introduces a new paradigm and ‘model’ to the existing literature. The methodology that characterizes the model is a ‘composite’ one that synthesizes methods and/or techniques such as ‘citation analysis’, ‘bibliometry’, ‘performance measurement’ and ‘bibliographic search’ which already exist in the relevant literature at both theoretical and practical levels. The purpose of the present article is to address and introduce the ‘conceptual model’ at a theoretical level.
